2 Claims. l

The present invention relates to the art of textile finishing machineryand is primarily concerned with an attachment or accessory to be usedwith a Palmer Roll.

A Palmer Roll is a widely used and well understood machine for finishingtextiles. In general, it comprises a large smooth surfaced drum which ismaintained at an elevated temperature and which rotates about its axis.An endless blanket of felt or similar material moves in contact with therotating drum throughout the greater portion of its circumference afterwhich it leaves the surface of the drum at one place and returns atanother adjacent thereto by passing over idling rollers. Cloth to betreated is dampened and fed in between the drum and is removed endlesslyat the point where the blanket is separated from the drum. During itspassage through the machine, the textile being treated is dried incontact with the polished surface of the drum and therefore leavesthedrum with one side thereof finished to a comparatively high gloss. Theopposite side of the cloth, however (the side in contact with theblanket), has a dull surface, thereby resulting in what is known `as atwo-sided effect.

One of the objects of the present invention is to provide a novelattachment for a Palmer Roll which enables the cloth being treated toberemoved from the machine with both sides thereof finished tosubstantially the same high gloss.

Another object is to provide a novel attachment for a Palmer Roll whichremoves the twosided effect from cloth treated by the Palmer Roll.

Still another object is to provide a novel attachment for a Palmer Rollwhich polishes the dull surface of textile material passing from thePalmer Roll.

Yet another object is to `accomplish all of the above in a simplemanner, at low cost and without increasing the time of treatment.

Other objects and advantages will become apparent from the followingdescription `of a preferred embodiment of my invention which isillustrated in the accompanying drawings.

In the drawings:

Fig. 1 is a side view of the portion of a Palmer Roll where the clothbeing treated enters and leaves the machine, the attachment or accessoryforming the subject matter of the present invention being shown mountedupon the Palmer Roll; and

Fig. 2 is a fractional front View of one side of the surface of the drumto the desired temperature. This drum has a ground and polishedcylindrical surface l2 and an endless blanket I4 of felt or similarmaterial in contact therewith. This blanket passes about idling rollers,not shown, and thence over an entrance roller IB where it is brought incontact with the drum face. From this point the blanket passes around.

15 the drum and leaves the drum around an exit yroller i8. The fabric tobe treated, indicated by the numeral 20, passes inwardly with theblanket over the roller IG and thencearound the drum il? with one sidethereof against the polished drum surface while the other side issupported by the blanket I4.

All of the above-described mechanism forms no part of the presentinvention, it comprising merely the essential elements of a standard andwell known Palmer Roll. Ordinarily the fabric 2U being treated isremoved from the surface of .the drum and separated from the blanket atthe roller I8 in the reverse manner that the fabric enters the machinein contact with the blanket around the roller l', The result i5 that thesurface of the cloth which was in contact with the drum has acomparatively high polish while the opposite surface which was inContact with the blanket I4 is dull.

I prevent this effect by the use of an attachment. indicated generallyby the numeral 22. This attachment comprises a bracket 24 at each sideof the machine which has one end thereof journaled as at `2li to the`shaft 28 of the blanket take-olf roll I8. The opposite end of each ofthese brackets is provided with a hole 30 through which a stud 32passes. These studs have their inner ends 34 threaded into tappedopenings in a portion 3B of the Palmer Roll frame. The opposite oroutward ends of the studs are threaded to adjusting nuts 38 which bearagainst the outer ends of coil springs lill. These springs surround thestuds and press with their inner ends against the outer surface of thebrackets 24.

At an intermediate point each bracket 24 carries a bearing block 42which is journaled to the shaft of what I refer to as a polishing roll44. This roll is free to rotate upon its axis and is urged against thesmooth surface of the Palmer Roll drum With any desired pressure,depending upon the adjustment of nuts 38. The axle 48 upon which theroll 44 is mounted carries a small sprocket 4B connected to a sprocket50 by a chain 52. The sprocket 59 is mounted at the end of the blankettake-off roll I8 so as to rotate therewith and the ratio of thesprockets 50 and 48 is such as to drive the roll 44 at a peripheralvelocity different than the linear velocity of the blanket I4,preferably at a higher velocity. In other words, if the radius of rollI8 plus the thickness of the blanket I4 is approximately the same as theradius of the roll 44, then the sprocket 50 should be larger than thesprocket 48. 1t will be appreciated, of course, that the roll 44 may beof any convenient size, it being necessary merely to adjust the sizes ofthe sprockets 59 and 48 so as to give the roll 44 a peripheral velocitysomewhat greater than the velocity of the blanket I4.

In using this attachment the cloth 2|] being treated is not brought outand separated from the drum I at the roll I8. Instead the blanket isseparated at this point but the fabric being treated continues incontact with the drum I and passes cut around the roll 44. When themachine is in operation, therefore, the side of the cloth in contactwith the drum ID receives a high polish during the major period oftreatment. At the point where the cloth is separated from the blanketI4, that is, at the roll I8, the back surface of the cloth will have thedull nish, but this surface is brought in contact subsequently with theroll 44 which has a higher peripheral velocity than the velocity ofmovement of the cloth 28 and therefore the roll 44 slips relative to thecloth and gives the outer surface thereof a polishing action.

I have found that when cloth is treated in a Palmer Roll machine whichhas my accessory attached thereto that by proper adjustment of the nut8S so as to urge the roll 44 against the back surface of the cloth withthe appropriate amount of pressure, the cloth being treated will leavethe machine with both surfaces thereof polished to substantially thesame high gloss and in fact it is diicult by subsequent examination todetermine which surface of the cloth was previously against the drum I0during treatment.

It will be appreciated that variations may be made in my attachmentwithout departing from the scope of the invention. As an example, byusing take-up rollers which pull upon the cloth so as to remove it fromthe machine under tension, it is possible to get much the same effect bydriving the roll 44 at a peripheral velocity less than that of theblanket. In either case, the roll 44 slips relative to the cloth beingtreated and therefore gives the polishing action.

Having described my invention, what I claim as new and useful and desireto secure by Letters Patent of the United States is:

l. Por a Palmer Roll machine having a rotating heated drum, a continuousblanket which lies against a substantial portion of the circumference ofthe drum and follows the rotation thereof, and

entering and exit rolls which maintain the blanket against the drum, theformer feeding the blanket against the drum and the latter separatingthe blanket therefrom, the two leaving an exposed portion of drumsurface not covered by the blanket wherein the material to be treated isintroduced against the exposed portion of drum surface; an accessory forremoving the two-sided effect from the material after passage throughthe machine comprising a smooth surfaced polishing roll disposedadjacent the exposed portion of the drum between the exit roll and thepoint of ymaterial entry, bracket means rotatably mounted upon the exitroll shaft for journaling the polishing roll-for rotation, means forresiliently urging the polishing roll toward the drum of the Palmer Rollin a position to nip the cloth emerging from the exit roll against thedrum, and drive means for rotating the polishing roll in a directionopposite to that of the drum and at a higher peripheral velocity thanthe linear velocity of the cloth passing through the machine.

2. For a Palmer Roll machine having a rotated heated drum, a continuousblanket which lies against a substantial portion of the circumference ofthe drum and follows the rotation thereof, and entering and exit rollswhich maintain the blanket against the drum, the former feeding theblanket against the drum and the latter separating the blankettherefrom, the two leaving an exposed portion of drum surface notcovered by the blanket wherein the material to be treated is introducedagainst the exposed portion of the drum surface; an accessory forremoving the two-sided effect from the material after passage throughthe machine comprising a smooth surfaced polishing roll disposedadjacent the exposed portion of the drum between the exit roll and thepoint of material entry, bracket means mounted on the Palmer Rollmachine for journalling the polishing roll for rotation, means forresiliently urging the polishing roll toward the drum of the Palmer Rollin a position to nip the -`4`5 'cloth emerging from the exit rollagainst the drum, and drive means for rotating the polishing roll in adirection opposite to that of the drum and `at a higher peripheralvelocity than the linear velocity of the cloth passing through themachine.
